deps: bump to controller-runtime v0.2.0, kubernetes-1.14.1, and helm v2.14.1

[estroz]

Description of the change: bump controller-runtime to v0.2.0 and helm to 2.14.0, both of which depend on kubernetes-1.14.x dependencies.

Motivation for the change: from #1388:

Address the commit kubernetes-sigs/controller-runtime@fc804a4

• How to make sure that the operator will only watch a List of namespaces? #1386
• Allow users to watch/cache N namespaces as follows.

        // Create a new Cmd to provide shared dependencies and start components
  mgr, err := manager.New(cfg, manager.Options{
  	NewCache: cache.MultiNamespacedCacheBuilder(namespaces),
  })

The compiler throws errors if there's no build identifier.

@camilamacedo86 @estroz Whichever PR lands in, we need a migration doc, I guess we can do this in a parallel PR for ease of reviewing?

[joelanford]

Also, what did we decide on what to do with this PR? Sit on it? Merge it into a separate branch? Merge it into master? Right now looks like it's targetting master.

[estroz]

@joelanford IIRC we agreed to merge with master because the original controller-runtime refactor was a much larger change than v0.1.x -> v0.2.x.

[joelanford]

@estroz Haha. I thought I heard the opposite based on the same premise. What I heard was "The separate branch for the original controller-runtime migration was a pain. Since the changes this time around are minimal relative to last time, a separate branch shouldn't be a big deal."

If we merge this to master, then we're either going to make a release on a non-stable version of controller-runtime, or we're going to be forced to wait until controller-runtime reaches a stable v0.2.0 release.

Hi @estroz,

Could you add here the follow commit?

• 1ad0fef

And upgrade the following deps as well?

[[constraint]]
  name = "github.com/sirupsen/logrus"
  version = "1.4.2"

[[constraint]]
  name = "github.com/spf13/cobra"
  version = "0.0.4"

Also, I think you can use the Changelog and just update the commit number c5bdaee

Really tks for the help on it 👍

[estroz]

@joelanford very possible I heard incorrectly. I'll make a refactor branch like we did last time.

Not sure how to handle the difference in version numbers in the CHANGELOG since #1612 was merged. So if those suggestions don't make sense, you can ignore them. Should we merge master into refactor/controller-runtime-v0.2.0?

Just one comment on the removed replace directive for the prometheus-operator dependency in go.mod.
